Yes, I think it does - in some cases anyway. People did choose to sell themselves into slavery, not to fulfill any kind of desire or yearning, but to avoid a worse fate, such as poverty and destitution. There are also instances where people of great accomplishment and ambition chose enslavement in order to attain wealth and power, and I believe that several important characters in history became slaves voluntarily and rose to great heights in China, Persia, Rome and many other places.
